Are aquarium diseases curable????

[Madame_X]

This is the biggest fish I have had to euthanize - it is somehow easier for me when they are small.

Oddly enough, I feel the same way. :? This is the biggest reason I haven't gotten a huge tank for Jack Dempseys or Oscars.

Is there a reliable on-line source for disease diagnosis? I cruise around and pick up bits and pieces here and there about certain diseases, and Pandora has a pretty good chart with pics of diseases, but where does everyone go to get info when they have a fish that is sick with something they are not familiar with?

This one is pretty good: http://www.fishdoc.co.uk/index.htm

But normally, I Google the illness I suspect and read everything I can. I figure the more info, the better and I tend to believe something is more likely to be true if I can find multiple articles to support it.
